Definitions

  • This invention relates to a rechargeable electric battery, preferably for a battery cell with means for calculating its SoH and SoC.
  • An electric battery is a device consisting of one or more electrochemical cells that can convert the stored chemical energy into electric current.
  • Electrochemical cells come in many shapes and sizes, such as cylindrical, button, prismatic, and bag.
  • bag cells have been gaining popularity in recent years as they offer a simple, flexible, and lightweight solution for battery design.
  • SoC State of Charge
  • SoH State of Health
  • the SoC represents the charge level of a battery in relation to its capacity.
  • the SoH represents the state of a battery compared to its ideal conditions.
  • the SoH of a battery will be at 100% at the time of manufacture and decrease over time and use.
  • the impedance in current batteries can be less than 1 mOhm; therefore, the measurement methods and necessary hardware must overcome specific requirements, substantially increasing the battery cost.
  • US2015132621A1 discloses an encasing film for a galvanic element has at least one force sensor for detecting an expansion state of the encasing film.
  • the encasing film is produced from an elastic and electrically insulating material, e.g., plastic.
  • the force sensor which has a strain gauge, is situated on a surface of the encasing film.
  • US2020076016A1 discloses a battery pouch.
  • the battery pouch including an outer layer and an inner layer disposed on the outer layer.
  • the inner layer including at least one sensor.
  • Another effective approach to predict the battery performance is based on real-time measurement of the change in the cell internal conditions that constitute the battery, using extremely sensitive and low-cost sensors.
  • a low-cost non-invasive sensor capable of detecting the cell volume variation is a very suitable tool to relate the mechanical stress to the cell chemical degradation, and thereby estimating the SoC and SoH of the battery.
  • One such method for measuring the cell surface deformation is the optical measurement, but this method has the disadvantage of excessive cost and integration difficulty into the battery.
  • Another method for measuring the cell surface deformation is using a deformation sensor glued on the cell surface, such as in Patent document US20200014074A1 .
  • This method has a main disadvantage in that the glue acts as an insulator between the deformation sensor and the cell surface, thereby interfering with the process of obtaining data, leading to errors, and interfering with the manufacturing process.
  • an object of this invention is a battery cell in the form of a bag, comprising a sensor fixed to the outside surface of the bag comprising a plurality of sensing elements of the same material, at least one conducting element and, optionally, at least one resistor element, the conducting element connecting the sensing element and/or the resistor element together,wherein the sensing element, the conducting element and/or the resistor element are respectively obtained by separately depositing portions of material of sensing element, of conducting element or of resistor element on the outside surface of the bag.
  • sensing element, conducting element or resistor element are composed of varied materials more suitable for the function they perform.
  • the sensing element is a deformation and/or temperature sensing element constituted by piezoresistive and/or thermoresistive material deposited on the outside surface of the bag.
  • one of the sensing elements is a deformation sensing element, configured for the detection of the surface deformation of the cell bag.
  • another sensing element is a temperature sensing element for measuring the surface temperature of the bag.
  • the cell comprises a plurality of sensing elements of the same sensing element material, thereby decreasing the manufacturing cost and ensuring that the measurements obtained are consistent among the different sensing elements.
  • the temperature sensing element is arranged substantially in the center of the bag, i.e., at a midway point of the bag equidistant from its outline.
  • the center of the outside surface of the bag is expected to be the position where the surface deformation of the bag is lower. In this way, the change in electrical resistance of the temperature sensing element would be related almost exclusively to the temperature of the material without interfering with the measurement of the deformation of the bag itself.
  • the temperature sensing element is substantially square in shape. This configuration allows the deformation of the temperature sensing element to be uniform, derived in turn by its central positioning, and consequently deforming the same in all directions. Therefore, the change in electrical resistance of the temperature sensing element with respect to the deformation of the outside surface of the bag is further decreased, improving the data acquisition.
  • the sensing element and the resistor element are connected to form a Wheatstone bridge. This ensures that the change in resistance of the sensing element due to the change in temperature of the material of the sensing element does not mask the change in resistance of the sensing element due to the surface deformation of the bag, resulting in a more accurate data acquisition.
  • the deposition of portions of material of sensing, resistor or conducting element is performed by sputtering or printing.
  • the sensor is fixed to the bag surface, eliminating the need for substrates or adhesives that could interfere with the data acquisition.
  • the sensing element, resistor element and/or conducting element are arranged forming different respective layers on the outside surface of the bag.
  • the manufacturing process of the sensor is homogenized in various stages, each one corresponding to the sensing element, resistor element and/or conducting element. This results in an optimization of each of the elements that constitutes the sensor.
  • the senor comprises a passivating layer applied to the sensing element, resistor element and conducting element.
  • This passivating layer increases the mechanical resistance of the sensing element, resistor element and conducting element to oxidation, surface scratches, etc.
  • the subject cell of the invention has an anode constituted by Lithium metal, and that the cell is selected among a lithium-sulfur, lithium-air, solid-state lithium ion or lithium-NMC cell, preferably the solid-state Li-S.
  • the subject cell configuration of the invention is of particular interest for the data acquisition of the properties of the outside surface of the bag in the case of Li-metal cells, since the bag undergoes significant volume changes during each charge and discharge cycle, due to the significant increase/decrease of the Li anode thickness. Therefore, with the above-described sensor configuration, such deformations are detected, obtaining a better estimation of the SoC and SoH of the battery.
  • the subject configuration of the invention of the various sensing elements comprised in the cell bag is particularly relevant, such that changes due to temperature and deformation are more effectively detected, for a better estimation of the SoC and SoH of the battery.
  • an object of the invention is a battery comprising said electrochemical cell for the calculation of its SoH and SoC.
  • Figure 1 shows an example of an electrochemical cell (1) of the state of the art, specifically showing a cell (1) with a bag (1.1), said bag (1.1) preferably having a rectangular shape.
  • the cell (1) comprises, at one end of the bag (1.1), a positive terminal (1.2), and at the opposite end protrudes a negative terminal (1.3), it is at said positive terminal (1.2) and negative terminal (1.3) where the connection with the electrical circuit outside the cell (1) occurs.
  • Figure 2 shows a cell (1) with a sensor (2) printed on the bag surface (1.1); in this example of preferred embodiment, the sensor (2) is comprised of two sensing elements (2.1.1, 2.1.2) and a resistor element (2.2) connected together. Specifically, the sensing elements are a deformation sensing element (2.1.1) and a temperature sensing element (2.1.2).
  • the material of the deformation sensing element (2.1.1) and the resistor element (2.2) is a piezoresistive material
  • the temperature sensing element (2.1.2) is a thermoresistive material.
  • the piezoresistive material has the property that its electrical resistance changes when it undergoes a mechanical stress or strain (traction or compression) that deforms it. Such change may be due either to the variation of the interatomic distance or the variation of the carrier concentrations.
  • the electrical resistance of piezoresistive materials can also depend on temperature, hence the need for the Wheatstone bridge configuration with the resistor element (2.2).
  • piezoresistive materials are: NiO, NiCr, TaN, TaNO, etc.
  • thermoresistive material has the property that its electrical resistance changes mainly when it undergoes a temperature change, without producing electrical potential, which makes it a truly relevant material for the conformation of temperature sensing elements (2.1.2).
  • thermistor materials are: NiO, Pt, Ag, etc.
  • the deformation sensing element (2.1.1), the temperature sensing element (2.1.2) and the resistor element (2.2) are made of the same material, preferably one that can function as piezoresistive and thermoresistive material.
  • the temperature sensing element (2.1.2) is preferably deposited in the center of the outside surface of the bag (1.1). At this location it is expected that the surface deformation of the bag (1.1) is uniform and the lowest of the entire bag surface (1.1). Thus, the interferences due to the outside surface deformation of the bag (1.1) in the temperature measurement are reduced, the temperature sensing element (2.1.2) being deformed exclusively by the action of temperature variations.
  • Said center of the outside surface of the bag (1.1) is defined by being at an equidistant distance between the four edges of the bag (1.1) when it houses a battery cell.
  • this temperature sensing element (2.1.2) has a substantially square shape, thus the change of electrical resistance of the temperature sensing element (2.1.2) due to cell deformation will be minimal. Uniform deformation is obtained in all directions of the material of the temperature sensing element (2.1.2), such that the measured data are more dependable.
  • a conducting element (3) is deposited on the outside surface of the bag (1.1) for transmitting the electrical signal.
  • This conducting element (3) comprises tracks (3.1) connecting the deformation sensing element (2.1.1), the temperature sensing element (2.1.2) and the resistor element (2.2) to terminals (3.2) preferably located on a margin of the outside surface of the bag (1.1) close to the positive terminal (1.2).
  • Such terminals would then connect a PCB for transmitting the data obtained from the sensors.
  • the selected methods for depositing the sensing elements (2.1.1, 2.1.2), resistor element (2.2) and conducting element (3) in the bag (1.1) are sputtering and applying the liquid material in the form of ink, for example, integrated in a roll-to-roll process. It should be noted that both processes are set forth as examples and are not limiting.
  • the sputtering method is a physical process in which the atoms of a solid material are vaporized by sputtering it with energetic ions. This process is widely used in the formation of thin films on materials, etching techniques, and analytical techniques.
  • a passivating layer (4) is deposited on the outside surface of the bag (1.1), such that it covers the deformation sensing element (2.1.1), temperature sensing element (2.1.2), the resistor element (2.2) and the conducting element (3), except for the terminals (3.2) of the conducting element (3).
  • This passivating layer (4) protects the deformation sensing element (2.1.1), temperature sensing element (2.1.2), the resistor element (2.2) and the conducting element (3) from surface scratches, oxidation, etc.
  • a non-limiting example of the passivating layer material (4) is Phoenix compound, a commercial compound for coating printed circuit boards.
  • the sputtering is divided into four phases, depositing the deformation sensing element (2.1.1), the temperature sensing element (2.1.2) and the resistor element (2.2), depositing the conducting element (3), curing of the deposited material on the bag surface (1.1) and depositing the passivating layer (4).
  • the deposition of the material of the deformation sensing element (2.1.1), temperature sensing element (2.1.2) and resistor element (2.2), preferably piezoresistive material such as NiO, is divided into three sub-phases:
  • the deposition of the conducting element material (3) preferably conducting material such as Ag, is divided into three sub-phases:
  • the material of the deformation sensing element (2.1.1), the temperature sensing element (2.1.2), the resistor element (2.2) and the conducting element (3) has been deposited, the material is cured for one hour at 120°C.
  • the deposition of portions of material for obtaining the deformation sensing element (2.1.1), the temperature sensing element (2.1.2), resistor element (2.2), conducting element (3) and the passivating layer (4) on the bag surface (1.1) is carried out by ink and/or pastes direct printing on the outside surface of the bag (1.1).
  • the bag (1.1) is a flexible material, it allows the integration of the entire manufacturing process in a roll-to-roll system, which in turn enables the processing of large surfaces at high speed.
  • the printing techniques currently available are numerous (flatbed & rotary screen-printing, inkjet printing, microdispensing, aerosol printing, flexographic printing, gravure, etc.) and all of them are valid for printing the sensor (2).
  • the minimum deformation and mean deformation show the most solid relationship with SoH. However, both are based on deformation values during each charge and discharge cycle and could be difficult to identify during normal operation. In this case, correlation coefficients of - 0,9437 and -0,9466 have been obtained for maximum deformation and mean deformation, respectively, showing a solid relationship again.
  • the deformation sensing element (2.1.1), the temperature sensing element (2.1.2) and the resistor element (2.2) are connected to the terminals (3.2) through the conducting element (3).
  • Such terminals (3.2) are connected to the PCB with the rest of the elements necessary for the calculation of the deformation and the temperature of the outside surface of the bag (1.1).
